IMPROVEMENT IN SCOURING AND SCRUBBING BRUSHES.

Specification forming part of Letters Patent No. 218,431, dated August12, 1879; application filed May 2, 1879.

To all whom it may concern:

Be it known that I, JosEPH S. DUNHAM,'of Salem, in the county of Salemand State of New Jersey, have invented a new and useful Improvement inScourin g and Scrubbing Brushes, which improvement is fully set forth inthe following specification and accompanying drawings, in which- Figurel is a side elevation of the brush embodying my invention. Fig. 2 is abottom View thereof. Fig. 3 is a longitudinal vertical section in linea: m, Fig. 2'.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a brush having a rubbing-face of angular orV-shaped rubber strips, whereby the dirt is directed to the side, so asto prevent clogging of the brush.

It also consists of a transverse strip connecting the angular strips atthe heel of the brush, for supporting the same.

It also consists of upwardly projecting flanges, which form a space forthe reception of the back of the brush, said flanges being beveled, soas to permit the ready nailing or tacking of the flanges to said back.

Referring to the drawings, A represents a series of angular or V-shapedstrips, which, arranged parallel, are formed of soft rubber, andattached to a backing, A. From the sides of the back A rise flanges B,which form a cavity in which is fitted the back 0 of the brush.

In order to secure the back in position, the upper edges of the flangesare beveled or thinned, as at a, and nails or tacks are driven throughsaid edges into the sides of the back, whereby the nails or tacks arereadily inserted, and their hold is firm, as the tend ency of theflanges to withdraw the nails or tacks is lessened by the beveling ofthe same.

In order to sustain the heel of the brush, I connect the ends of thestrips A at said heel by a transverse strip, D, which supports andstrengthens said end.

It will be seen that the rubbing-surface produces considerable frictionwith the floor, step, or other article against which it is rubbed, andowing to the V or angular form of the strips A, the dirt, water, &c.,are directed to the open sides or spaces between the strips, wherebythere is no packing of the dirt, &c., and consequently no clogging ofthe brush.

The frictional nature of the strips A causes the effective scouring andcleaning of articles, and comparatively dries the same Withoutsubsequent use of rags.

It will be noticed that the strips A, strip D, backing A, and flanges Bare made of rubber in one piece.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A scrubbing-brush having oblique rubber serubbingridges and a transverserubber bracing ridge, said scrubbing and bracing ridge being formed inone piece with the rubber backing, so as to retain permanently the samerelative positions and constitute one article.
